Abstract:

Parallel simulation is emerging as the dominant technique for studying
parallel computers. However, the interconnection networks of these
machines can be modeled at many different levels of abstraction,
allowing researchers to trade off accuracy and performance. In this
paper, we use the Wisconsin Wind Tunnel, a parallel simulator for
cache-coherent shared-memory machines, to study the trade-offs of
accuracy versus performance for six different network simulation
models. We evaluate these models for a variety of parallel
applications, cache-coherence protocols, and topologies. We show that
only the two most expensive models-which model contention at
individual links-are robust in the presence of high network loads or
non-uniform traffic patterns.
